This invention relates to insect insulators and with the bottom pan. The flanges of the support has for an object to provide a simplified device extend transversely of the bottom pan and the web which will frustrate entrance of termites yintov extends longitudinally of the bottom pan as best building foundations and exterminate the terv y'shown in Figure 5. The flanges and web are 5 mites.
